During the summer, the chain of bookstores expanded its assortment with a new collection of popular publications from "Our Format". The selection includes Howard Schultz's work on Starbucks, William Ury's book on how to say "no", Hal Elrod's work on early rising, Niall Ferguson's study on the reasons for the West's success, and others. These editions can be purchased at more than 50 OKKO gas stations located on the busiest highways.

Time magazine included the author of "Civilization" — British historian and Harvard professor Niall Ferguson — in the list of the hundred most influential people on the planet. Based on his work, the BBC prepared a series of programs. "Civilization" is a concise overview of European history over the last six centuries, presented on a global scale and written vividly, figuratively, and sometimes boldly. Ferguson's strength is his ability to present complex topics accessibly but without oversimplification, which allows him to hold the reader's interest throughout the book.

The work of the chairman of Starbucks' board of directors is also devoted to history, but not world history, rather the history of a single company that has already acquired cult status. The subtitle of Schultz's bestseller — "It All Started with a Cup of Coffee" — tells about the creation of a brand under which 25 thousand coffee shops now operate in 70 countries. Starbucks' path to success can inspire entrepreneurs to bolder ambitions, and also demonstrates how important it is to care about reputation from the first steps in business and strengthen the brand's connection with customers.

For those wishing to work on themselves, put things in order, manage time wisely, and build relationships with others, there are many useful recommendations in the publications "The Power of a Positive No: How to Say No and Still Get to Yes", "The Miracle Morning: The Not-So-Obvious Secret Guaranteed to Transform Your Life (Before 8AM)", "The No Asshole Rule: Building a Civilized Workplace and Surviving One That Isn't", "TED Talks: The Official TED Guide to Public Speaking". Walter Isaacson enthusiastically narrates breakthrough ideas in digital technology in his work "The Innovators". Additionally, at OKKO there are also works of the business-philosophical genre that have already become canonical, for example, the trilogy "Atlas Shrugged" by Ayn Rand or "The Black Swan" by Nassim Nicholas Taleb.
